A ferry takes several trips between points A and B. It moves at a constant speed of 0.35 miles/minute and takes the same route o

n each trip. The total duration of a round trip from point A to point B and back is 80 minutes, ignoring the time spent stopped at point B. If d is the ferry’s distance from point A in miles and t is the time in minutes, which equation models the ferry’s distance from point A for the duration of the trip?
A.
d = -|0.35t – 40| + 40
B.
d = -|0.35t – 80| + 80
C.
d = -|0.35t – 28| + 28
D.
d = -|0.35t – 14| + 14

The answer is  -|0.35 t -14| +14

<u>Step-by-step explanation</u>:

The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.

Step-by-step explanation:

Adding 10 to both sides of the original equation gets us q = 6(r + 1) + 10. Since q is equal to h(r), we get h(r) = 6(r + 1) + 10 = 6r + 16.

bookstore ordered 1,528 packs of pens and 1,823 packs of pencils at the prices shown. how much did the bookstore spend on pens?
IgorC [24]
I found that the given prices are $ 4 per pack of pens and $ 3 per pack of penciles.

The question is how much the bookstore spent on pens.

Then you have to multiply the number packs of pens, which is 1,528, times the price per pack pens which is $ 4.

So, the answer is: 1528 packs of pens * $ 4 / pack of pens = $6112.

What is the average rate of change from −3 to 0 of the function represented by the graph?
aleksandrvk [35]

Answer:

-0.5

Step-by-step explanation:

The average rate of change from a to b:

[f(b) - f(a)]/(b - a)

Look in the graph for the function values at x = -3 and x = 0.

f(-3) = 2

f(0) = 0.5

average rate of change =

= [f(-3) - f(0)]/(-3 - 0)

= [2 - 0.5]/(-3)

= 1.5/(-3)

= -0.5
